If you take out Haley's AA performance in 2015, which was horrible, you will see that he has had a pretty stellar minor league career. Therefore, I am in the "wait and see what we have here" mode.

Dunno about "stellar". The guy tracked through the minors at roughly the league average age while posting 3.6/7.8 BB/K rates.

 

We all love to bash Tonkin and, by comparison, he tracked through the minors 1.5-2.0 years younger than league average age while posting 2.2/9.3 BB/K rates.

I agree with the article.

 

If it were up to me, I would go with Mejia for starter #5, return Haley, start Berrios in AAA, and add Duffey (long man) and Chargois to the Bullpen.

 

Haley has been unimpressive, but if the brass insists on keeping him, then I would hide him in the bullpen and Chargois would be sent down.

Rest assured that by June 1, the pitching staff will have been jostled numerous times due to injury or ineffectiveness. So, whoever happens to go north in April isn't terribly significant except for Mr. Rule 5 guy.
